As previously agreed to, North Korea returned remains of American soldiers killed in the Korean Conflict last week. What does this say about whether that country intends to abide by terms of its recent agreement the United States?

Not much. This was the easiest part of the deal for North Korea to comply with.

A lot. North Korea has disregarded or reneged on all previous negotiation terms with American administrations for the past quarter century.

It's a start, but the key is real proof that North Korea is dismantling its nuclear arms capabilities, and that hasn't come yet.
